| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch "KVM: fix !SMP build error" change the way smp_call_function() actually uses the passed in function names on non-SMP builds. So previously it was never caught that the function passed in was never actually defined. This causes a build error on ppc64_defconfig + CONFIG_SMP=n: arch/powerpc/mm/tlb_64.c: In function 'pgtable_free_now': arch/powerpc/mm/tlb_64.c:71: error: 'pte_free_smp_sync' undeclared (first use in this function) arch/powerpc/mm/tlb_64.c:71: error: (Each undeclared identifier is reported only once arch/powerpc/mm/tlb_64.c:71: error: for each function it appears in.) So we need to define it even if CONFIG_SMP is off. Either that or ifdef out the smp_call_function() call, but that's ugly.

| * | [POWERPC] Avoid unpaired stwcx. on some processorsBecky Bruce2007-11-132-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The context switch code in the kernel issues a dummy stwcx. to clear the reservation, as recommended by the architecture. However, some processors can have issues if this stwcx to address A occurs while the reservation is already held to a different address B. To avoid this problem, the dummy stwcx. needs to be paired with a dummy lwarx to the same address. This adds the dummy lwarx, and creates a cpu feature bit to indicate which cpus are affected.

If we happen to build with one of those compilers we will get SPE instructions in random kernel code. Today we only allow basic interger code in the kernel and FP, AltiVec, or SPE in special explicit locations that have handled the proper saving and restoring of the register state (since on uniprocessor we lazy context switch the register state for FP, AltiVec, and SPE). -mno-spe disables the compiler for automatically generating SPE instructions without our knowledge.

* | | x86 - 32-bit ptrace emulation mishandles 6th argChuck Ebbert2007-11-101-13/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ jdike - Pushing Chuck's patch - see http://lkml.org/lkml/2005/9/16/261 for some history and a test program. UML is also broken without this patch - its processes get SIGBUS from the corrupt 6th argument to mmap being interpretted as a file offset ] When the 32-bit vDSO is used to make a system call, the %ebp register for the 6th syscall arg has to be loaded from the user stack (where it's pushed by the vDSO user code). The native i386 kernel always does this before stopping for syscall tracing, so %ebp can be seen and modified via ptrace to access the 6th syscall argument. The x86-64 kernel fails to do this, presenting the stack address to ptrace instead. This makes the %rbp value seen by 64-bit ptrace of a 32-bit process, and the %ebp value seen by a 32-bit caller of ptrace, both differ from the native i386 behavior. This patch fixes the problem by putting the word loaded from the user stack into %rbp before calling syscall_trace_enter, and reloading the 6th syscall argument from there afterwards (so ptrace can change it). This makes the behavior match that of i386 kernels.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The addr argument to PTRACE_GET_THREAD_AREA and PTRACE_SET_THREAD_AREA is not a magic constant. It's derived from the segment register values being used, which are computed originally from the index used with set_thread_area. The value does not need to match what a native i386 kernel would accept. It needs to match the segment selectors that can actually be in use in this 32-bit process. The 64-bit ptrace support for PTRACE_GET_THREAD_AREA (normally used only on 32-bit processes) is correct, but the 32-bit emulation of ptrace is broken.

This fixes the problem by pulling the code in update_process_times that updates utime and stime into a separate function called account_process_tick. If CONFIG_VIRT_CPU_ACCOUNTING is not defined, there is a version of account_process_tick in kernel/timer.c that simply accounts a whole tick to either utime or stime as before. If CONFIG_VIRT_CPU_ACCOUNTING is defined, then arch code gets to implement account_process_tick. This also lets us simplify the s390 code a bit; it means that the s390 timer interrupt can now call update_process_times even when CONFIG_VIRT_CPU_ACCOUNTING is turned on, and can just implement a suitable account_process_tick(). account_process_tick() now takes the task_struct * as an argument.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves copy_{to,from}_user_page() out-of-line on SH-4 and converts for the kmap_coherent() API. Based on the MIPS implementation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the kmap_coherent() API in place, this is trivial to implement, and lets us avoid the cache flush in certain cases. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The current code is broken and hasn't built in some time, so just kill it off and get the board working again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

ST maintains their own out-of-tree changes and rebases occasionally, and that's ultimately where all of the ST40 users go anyways. In order for the ST40 code to be brought up to date most of the stuff removed in this changeset would have to be rewritten anyways, so there's very little benefit in keeping the remnants around either.
